A rectangular workpiece has the following original dimensions: 2a = 120 mm, h = 40 mm and width = 25 mm (see Fig. 6.5). The metal has a strength coefficient of 530 MPa and a strain hardening exponent of 0.26. It is being forged in-plane strain with u = 0.25. Calculate the force required at a reduction of 25%. Use the average- pressure formula.

A long, copper strip, 500 mm wide, 3 mm thick, was found to have 450 MPa yield stress. The strip is required to be rolled in order to reduce its thickness. In the rolling process, the width remains practically unchanged while the rolls apply pressure in the thickness direction. An additional tension of 150 kN is applied in the longitudinal direction to assist the forming process. Ignoring the change in the width and any friction effects, determine what roll pressure would just cause deformation: according to the Von Mises yield criterion. according to the Tresca yield criterion. Material properties in the elastic range: E=75 GPa, v=0.4. (a) (b)
